Mobile terminal and controlling method thereof

ABSTRACT

A mobile terminal and controlling method thereof are disclosed. The present invention includes a display unit configured to display an image including at least one object on a screen and a controller searching for at least one associated information on the object using a partial image corresponding to the object in the image, the controller displaying the searched associated information. Accordingly, when a user searches for an information on a specific object in an image using an image search function, it is unnecessary for the user to crop a partial image corresponding to the specific object in the image one by one. Instead, a mobile terminal automatically recognizes the specific object in the image and is then able to search for at least one associated information on the specific object using a partial image of the automatically recognized specific object.

Pursuant to 35 U.S.C §119(a), this application claims the benefit of earlier of earlier filing date and right of priority to Korean Application No. 10-2014-0002291, filed on Jan. 8, 2014, the contents of which are hereby incorporated by reference herein in their entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a mobile terminal, and more particularly, to a mobile terminal and a method of controlling the mobile terminal.

2. Discussion of the Related Art

Terminals may be generally classified as mobile/portable terminals or stationary terminals according to their mobility. Mobile terminals may also be classified as handheld terminals or vehicle mounted terminals according to whether or not a user can directly carry the terminal.

Mobile terminals have become increasingly more functional. Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files via a speaker system, and displaying images and video on a display. Some mobile terminals include additional functionality which supports game playing, while other terminals are configured as multimedia players. More recently, mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of content such as videos and television programs.

Efforts are ongoing to support and increase the functionality of mobile terminals. Such efforts include software and hardware improvements, as well as changes and improvements in the structural components.

Currently, a prescribed web browser available for a mobile terminal such as a smartphone provides an image search function. According to the image search function, if a URL, to which a search target image is uploaded, is pasted on a search window of the web browser or a search target image is entered in the search window, the web browser searches a web for information containing the image and then provides a result of the search to a user.

However, when a user searches an image for a specific object (e.g., a watch) using the image search function of the web browser for the purpose of the search for an information of the specific object in the image, it is inconvenient for the user to search for the specific object in a manner of creating a new image by cropping the specific object from the image and then entering the new image in the search window of the web browser one by one.

Data (for example, audio, video, image, and the like) is obtained by the input unit 120 and may be analyzed and processed by controller 180 according to device parameters, user commands, and combinations thereof.

The sensing unit 140 is typically implemented using one or more sensors configured to sense internal information of the mobile terminal, the surrounding environment of the mobile terminal, user information, and the like. For example, in FIG. 1A, the sensing unit 140 is shown having a proximity sensor 141 and an illumination sensor 142.

The mobile terminal 100 may be configured to utilize information obtained from sensing unit 140, and in particular, information obtained from one or more sensors of the sensing unit 140, and combinations thereof.

The output unit 150 is typically configured to output various types of information, such as audio, video, tactile output, and the like. The output unit 150 is shown having a display unit 151, an audio output module 152, a haptic module 153, and an optical output module 154.

The display unit 151 may have an inter-layered structure or an integrated structure with a touch sensor in order to facilitate a touch screen. The touch screen may provide an output interface between the mobile terminal 100 and a user, as well as function as the user input unit 123 which provides an input interface between the mobile terminal 100 and the user.

The interface unit 160 serves as an interface with various types of external devices that can be coupled to the mobile terminal 100. The interface unit 160, for example, may include any of wired or wireless ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, and the like. In some cases, the mobile terminal 100 may perform assorted control functions associated with a connected external device, in response to the external device being connected to the interface unit 160.

The memory 170 is typically implemented to store data to support various functions or features of the mobile terminal 100. For instance, the memory 170 may be configured to store application programs executed in the mobile terminal 100, data or instructions for operations of the mobile terminal 100, and the like. Some of these application programs may be downloaded from an external server via wireless communication. Other application programs may be installed within the mobile terminal 100 at time of manufacturing or shipping, which is typically the case for basic functions of the mobile terminal 100 (for example, receiving a call, placing a call, receiving a message, sending a message, and the like). It is common for application programs to be stored in the memory 170, installed in the mobile terminal 100, and executed by the controller 180 to perform an operation (or function) for the mobile terminal 100.

The controller 180 typically functions to control overall operation of the mobile terminal 100, in addition to the operations associated with the application programs.

The controller 180 may provide or process information or functions appropriate for a user by processing signals, data, information and the like, which are input or output by the various components depicted in FIG. 1A, or activating application programs stored in the memory 170. As one example, the controller 180 controls some or all of the components illustrated in FIGS. 1A-1C according to the execution of an application program that have been stored in the memory 170.

The power supply unit 190 can be configured to receive external power or provide internal power in order to supply appropriate power required for operating elements and components included in the mobile terminal 100. The power supply unit 190 may include a battery, and the battery may be configured to be embedded in the terminal body, or configured to be detachable from the terminal body.

Referring still to FIG. 1A, various components depicted in this figure will now be described in more detail. Regarding the wireless communication unit 110, the broadcast receiving module 111 is typically configured to receive a broadcast signal and/or broadcast associated information from an external broadcast managing entity via a broadcast channel. The broadcast channel may include a satellite channel, a terrestrial channel, or both. In some embodiments, two or more broadcast receiving modules 111 may be utilized to facilitate simultaneously receiving of two or more broadcast channels, or to support switching among broadcast channels.

The mobile communication module 112 can transmit and/or receive wireless signals to and from one or more network entities. Typical examples of a network entity include a base station, an external mobile terminal, a server, and the like. Such network entities form part of a mobile communication network, which is constructed according to technical standards or communication methods for mobile communications (for example, Global System for Mobile Communication (GSM), Code Division Multi Access (CDMA), CDMA2000 (Code Division Multi Access 2000), EV-DO (Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), Wideband CDMA (WCDMA), High Speed Downlink Packet access (HSDPA), HSUPA (High Speed Uplink Packet Access), Long Term Evolution (LTE) , LTE-A (Long Term Evolution-Advanced), and the like). Examples of wireless signals transmitted and/or received via the mobile communication module 112 include audio call signals, video (telephony) call signals, or various formats of data to support communication of text and multimedia messages.

The wireless Internet module 113 is configured to facilitate wireless Internet access. This module may be internally or externally coupled to the mobile terminal 100. The wireless Internet module 113 may transmit and/or receive wireless signals via communication networks according to wireless Internet technologies.

Examples of such wireless Internet access include Wireless LAN (WLAN), Wireless Fidelity (Wi-Fi), Wi-Fi Direct, Digital Living Network Alliance (DLNA), Wireless Broadband (WiBro), Worldwide Interoperability for Microwave Access (WiMAX), High Speed Downlink Packet Access (HSDPA), HSUPA (High Speed Uplink Packet Access), Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced), and the like. The wireless Internet module 113 may transmit/receive data according to one or more of such wireless Internet technologies, and other Internet technologies as well.

In some embodiments, when the wireless Internet access is implemented according to, for example, WiBro, HSDPA,HSUPA, GSM, CDMA, WCDMA, LTE, LTE-A and the like, as part of a mobile communication network, the wireless Internet module 113 performs such wireless Internet access. As such, the Internet module 113 may cooperate with, or function as, the mobile communication module 112.

The short-range communication module 114 is configured to facilitate short-range communications. Suitable technologies for implementing such short-range communications include BLUETOOTH, Radio Frequency IDentification (RFID), Infrared Data Association (IrDA), Ultra-WideBand (UWB), ZigBee, Near Field Communication (NFC), Wireless-Fidelity (Wi-Fi), Wi-Fi Direct, Wireless USB (Wireless Universal Serial Bus), and the like. The short-range communication module 114 in general supports wireless communications between the mobile terminal 100 and a wireless communication system, communications between the mobile terminal 100 and another mobile terminal 100, or communications between the mobile terminal and a network where another mobile terminal 100 (or an external server) is located, via wireless area networks. One example of the wireless area networks is a wireless personal area networks.

In some embodiments, another mobile terminal (which may be configured similarly to mobile terminal 100) may be a wearable device, for example, a smart watch, a smart glass or a head mounted display (HMD), which is able to exchange data with the mobile terminal 100 (or otherwise cooperate with the mobile terminal 100). The short-range communication module 114 may sense or recognize the wearable device, and permit communication between the wearable device and the mobile terminal 100. In addition, when the sensed wearable device is a device which is authenticated to communicate with the mobile terminal 100, the controller 180, for example, may cause transmission of data processed in the mobile terminal 100 to the wearable device via the short-range communication module 114. Hence, a user of the wearable device may use the data processed in the mobile terminal 100 on the wearable device. For example, when a call is received in the mobile terminal 100, the user may answer the call using the wearable device. Also, when a message is received in the mobile terminal 100, the user can check the received message using the wearable device.

The location information module 115 is generally configured to detect, calculate, derive or otherwise identify a position of the mobile terminal. As an example, the location information module 115 includes a Global Position System (GPS) module, a Wi-Fi module, or both. If desired, the location information module 115 may alternatively or additionally function with any of the other modules of the wireless communication unit 110 to obtain data related to the position of the mobile terminal.

As one example, when the mobile terminal uses a GPS module, a position of the mobile terminal may be acquired using a signal sent from a GPS satellite. As another example, when the mobile terminal uses the Wi-Fi module, a position of the mobile terminal can be acquired based on information related to a wireless access point (AP) which transmits or receives a wireless signal to or from the Wi-Fi module.

The input unit 120 may be configured to permit various types of input to the mobile terminal 120. Examples of such input include audio, image, video, data, and user input. Image and video input is often obtained using one or more cameras 121. Such cameras 121 may process image frames of still pictures or video obtained by image sensors in a video or image capture mode. The processed image frames can be displayed on the display unit 151 or stored in memory 170. In some cases, the cameras 121 may be arranged in a matrix configuration to permit a plurality of images having various angles or focal points to be input to the mobile terminal 100. As another example, the cameras 121 may be located in a stereoscopic arrangement to acquire left and right images for implementing a stereoscopic image.

The microphone 122 is generally implemented to permit audio input to the mobile terminal 100. The audio input can be processed in various manners according to a function being executed in the mobile terminal 100. If desired, the microphone 122 may include assorted noise removing algorithms to remove unwanted noise generated in the course of receiving the external audio.

The user input unit 123 is a component that permits input by a user. Such user input may enable the controller 180 to control operation of the mobile terminal 100. The user input unit 123 may include one or more of a mechanical input element (for example, a key, a button located on a front and/or rear surface or a side surface of the mobile terminal 100, a dome switch, a jog wheel, a jog switch, and the like), or a touch-sensitive input, among others. As one example, the touch-sensitive input may be a virtual key or a soft key, which is displayed on a touch screen through software processing, or a touch key which is located on the mobile terminal at a location that is other than the touch screen. On the other hand, the virtual key or the visual key may be displayed on the touch screen in various shapes, for example, graphic, text, icon, video, or a combination thereof.

The sensing unit 140 is generally configured to sense one or more of internal information of the mobile terminal, surrounding environment information of the mobile terminal, user information, or the like. The controller 180 generally cooperates with the sending unit 140 to control operation of the mobile terminal 100 or execute data processing, a function or an operation associated with an application program installed in the mobile terminal based on the sensing provided by the sensing unit 140. The sensing unit 140 may be implemented using any of a variety of sensors, some of which will now be described in more detail.

The proximity sensor 141 may include a sensor to sense presence or absence of an object approaching a surface, or an object located near a surface, by using an electromagnetic field, infrared rays, or the like without a mechanical contact. The proximity sensor 141 may be arranged at an inner region of the mobile terminal covered by the touch screen, or near the touch screen.

The proximity sensor 141, for example, may include any of a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and the like. When the touch screen is implemented as a capacitance type, the proximity sensor 141 can sense proximity of a pointer relative to the touch screen by changes of an electromagnetic field, which is responsive to an approach of an object with conductivity. In this case, the touch screen (touch sensor) may also be categorized as a proximity sensor.

The term “proximity touch” will often be referred to herein to denote the scenario in which a pointer is positioned to be proximate to the touch screen without contacting the touch screen. The term “contact touch” will often be referred to herein to denote the scenario in which a pointer makes physical contact with the touch screen. For the position corresponding to the proximity touch of the pointer relative to the touch screen, such position will correspond to a position where the pointer is perpendicular to the touch screen. The proximity sensor 141 may sense proximity touch, and proximity touch patterns (for example, distance, direction, speed, time, position, moving status, and the like).

In general, controller 180 processes data corresponding to proximity touches and proximity touch patterns sensed by the proximity sensor 141, and cause output of visual information on the touch screen. In addition, the controller 180 can control the mobile terminal 100 to execute different operations or process different data according to whether a touch with respect to a point on the touch screen is either a proximity touch or a contact touch.

A touch sensor can sense a touch applied to the touch screen, such as display unit 151, using any of a variety of touch methods. Examples of such touch methods include a resistive type, a capacitive type, an infrared type, and a magnetic field type, among others.

As one example, the touch sensor may be configured to convert changes of pressure applied to a specific part of the display unit 151, or convert capacitance occurring at a specific part of the display unit 151, into electric input signals. The touch sensor may also be configured to sense not only a touched position and a touched area, but also touch pressure and/or touch capacitance. A touch object is generally used to apply a touch input to the touch sensor. Examples of typical touch objects include a finger, a touch pen, a stylus pen, a pointer, or the like.

When a touch input is sensed by a touch sensor, corresponding signals may be transmitted to a touch controller. The touch controller may process the received signals, and then transmit corresponding data to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched. Here, the touch controller may be a component separate from the controller 180, the controller 180, and combinations thereof.

In some embodiments, the controller 180 may execute the same or different controls according to a type of touch object that touches the touch screen or a touch key provided in addition to the touch screen. Whether to execute the same or different control according to the object which provides a touch input may be decided based on a current operating state of the mobile terminal 100 or a currently executed application program, for example.

The touch sensor and the proximity sensor may be implemented individually, or in combination, to sense various types of touches. Such touches includes a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch, and the like.

If desired, an ultrasonic sensor may be implemented to recognize position information relating to a touch object using ultrasonic waves. The controller 180, for example, may calculate a position of a wave generation source based on information sensed by an illumination sensor and a plurality of ultrasonic sensors. Since light is much faster than ultrasonic waves, the time for which the light reaches the optical sensor is much shorter than the time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source may be calculated using this fact. For instance, the position of the wave generation source may be calculated using the time difference from the time that the ultrasonic wave reaches the sensor based on the light as a reference signal.

The camera 121 typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor.

Implementing the camera 121 with a laser sensor may allow detection of a touch of a physical object with respect to a 3D stereoscopic image. The photo sensor may be laminated on, or overlapped with, the display device. The photo sensor may be configured to scan movement of the physical object in proximity to the touch screen. In more detail, the photo sensor may include photo diodes and transistors at rows and columns to scan content received at the photo sensor using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor may calculate the coordinates of the physical object according to variation of light to thus obtain position information of the physical object.

The display unit 151 is generally configured to output information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program executing at the mobile terminal 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.

In some embodiments, the display unit 151 may be implemented as a stereoscopic display unit for displaying stereoscopic images. A typical stereoscopic display unit may employ a stereoscopic display scheme such as a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like.

The audio output module 152 is generally configured to output audio data. Such audio data may be obtained from any of a number of different sources, such that the audio data may be received from the wireless communication unit 110 or may have been stored in the memory 170. The audio data may be output during modes such as a signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module 152 can provide audible output related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed by the mobile terminal 100. The audio output module 152 may also be implemented as a receiver, a speaker, a buzzer, or the like.

A haptic module 153 can be configured to generate various tactile effects that a user feels, perceive, or otherwise experience. A typical example of a tactile effect generated by the haptic module 153 is vibration. The strength, pattern and the like of the vibration generated by the haptic module 153 can be controlled by user selection or setting by the controller. For example, the haptic module 153 may output different vibrations in a combining manner or a sequential manner.

Besides vibration, the haptic module 153 can generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving to contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch to the skin, a contact of an electrode, electrostatic force, an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat, and the like.

The haptic module 153 can also be implemented to allow the user to feel a tactile effect through a muscle sensation such as the user's fingers or arm, as well as transferring the tactile effect through direct contact. Two or more haptic modules 153 may be provided according to the particular configuration of the mobile terminal 100.

An optical output module 154 can output a signal for indicating an event generation using light of a light source. Examples of events generated in the mobile terminal 100 may include message reception, call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like.

A signal output by the optical output module 154 may be implemented in such a manner that the mobile terminal emits monochromatic light or light with a plurality of colors. The signal output may be terminated as the mobile terminal senses that a user has checked the generated event, for example.

The interface unit 160 serves as an interface for external devices to be connected with the mobile terminal 100. For example, the interface unit 160 can receive data transmitted from an external device, receive power to transfer to elements and components within the mobile terminal 100, or transmit internal data of the mobile terminal 100 to such external device. The interface unit 160 may include wired or wireless headset ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, or the like.

The identification module may be a chip that stores various information for authenticating authority of using the mobile terminal 100 and may include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM), and the like. In addition, the device having the identification module (also referred to herein as an “identifying device”) may take the form of a smart card. Accordingly, the identifying device can be connected with the terminal 100 via the interface unit 160.

When the mobile terminal 100 is connected with an external cradle, the interface unit 160 can serve as a passage to allow power from the cradle to be supplied to the mobile terminal 100 or may serve as a passage to allow various command signals input by the user from the cradle to be transferred to the mobile terminal there through. Various command signals or power input from the cradle may operate as signals for recognizing that the mobile terminal is properly mounted on the cradle.

The memory 170 can store programs to support operations of the controller 180 and store input/output data (for example, phonebook, messages, still images, videos, etc.). The memory 170 may store data related to various patterns of vibrations and audio which are output in response to touch inputs on the touch screen.

The memory 170 may include one or more types of storage mediums including a Flash memory, a hard disk, a solid state disk, a silicon disk, a multimedia card micro type, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read-Only Memory (ROM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a Programmable Read-Only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. The mobile terminal 100 may also be operated in relation to a network storage device that performs the storage function of the memory 170 over a network, such as the Internet.

The controller 180 may typically control the general operations of the mobile terminal 100. For example, the controller 180 may set or release a lock state for restricting a user from inputting a control command with respect to applications when a status of the mobile terminal meets a preset condition.

The controller 180 can also perform the controlling and processing associated with voice calls, data communications, video calls, and the like, or perform pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively. In addition, the controller 180 can control one or a combination of those components in order to implement various exemplary embodiments disclosed herein.

The power supply unit 190 receives external power or provides internal power and supply the appropriate power required for operating respective elements and components included in the mobile terminal 100. The power supply unit 190 may include a battery, which is typically rechargeable or be detachably coupled to the terminal body for charging.

The power supply unit 190 may include a connection port. The connection port may be configured as one example of the interface unit 160 to which an external charger for supplying power to recharge the battery is electrically connected.

As another example, the power supply unit 190 may be configured to recharge the battery in a wireless manner without use of the connection port. In this example, the power supply unit 190 can receive power, transferred from an external wireless power transmitter, using at least one of an inductive coupling method which is based on magnetic induction or a magnetic resonance coupling method which is based on electromagnetic resonance.

Various embodiments described herein may be implemented in a computer-readable medium, a machine-readable medium, or similar medium using, for example, software, hardware, or any combination thereof.

Referring now to FIGS. 1B and 1C, the mobile terminal 100 is described with reference to a bar-type terminal body. However, the mobile terminal 100 may alternatively be implemented in any of a variety of different configurations. Examples of such configurations include watch-type, clip-type, glasses-type, or as a folder-type, flip-type, slide-type, swing-type, and swivel-type in which two and more bodies are combined with each other in a relatively movable manner, and combinations thereof. Discussion herein will often relate to a particular type of mobile terminal (for example, bar-type, watch-type, glasses-type, and the like). However, such teachings with regard to a particular type of mobile terminal will generally apply to other types of mobile terminals as well.

The mobile terminal 100 will generally include a case (for example, frame, housing, cover, and the like) forming the appearance of the terminal. In this embodiment, the case is formed using a front case 101 and a rear case 102. Various electronic components are incorporated into a space formed between the front case 101 and the rear case 102. At least one middle case may be additionally positioned between the front case 101 and the rear case 102.

The display unit 151 is shown located on the front side of the terminal body to output information. As illustrated, a window 151 a of the display unit 151 may be mounted to the front case 101 to form the front surface of the terminal body together with the front case 101.

In some embodiments, electronic components may also be mounted to the rear case 102. Examples of such electronic components include a detachable battery 191, an identification module, a memory card, and the like. Rear cover 103 is shown covering the electronic components, and this cover may be detachably coupled to the rear case 102. Therefore, when the rear cover 103 is detached from the rear case 102, the electronic components mounted to the rear case 102 are externally exposed.

As illustrated, when the rear cover 103 is coupled to the rear case 102, a side surface of the rear case 102 is partially exposed. In some cases, upon the coupling, the rear case 102 may also be completely shielded by the rear cover 103. In some embodiments, the rear cover 103 may include an opening for externally exposing a camera 121 b or an audio output module 152 b.

The cases 101, 102, 103 may be formed by injection-molding synthetic resin or may be formed of a metal, for example, stainless steel (STS), aluminum (Al), titanium (Ti), or the like.

As an alternative to the example in which the plurality of cases form an inner space for accommodating components, the mobile terminal 100 may be configured such that one case forms the inner space. In this example, a mobile terminal 100 having a uni-body is formed in such a manner that synthetic resin or metal extends from a side surface to a rear surface.

If desired, the mobile terminal 100 may include a waterproofing unit (not shown) for preventing introduction of water into the terminal body. For example, the waterproofing unit may include a waterproofing member which is located between the window 151 a and the front case 101, between the front case 101 and the rear case 102, or between the rear case 102 and the rear cover 103, to hermetically seal an inner space when those cases are coupled.

FIGS. 1B and 1C depict certain components as arranged on the mobile terminal. However, it is to be understood that alternative arrangements are possible and within the teachings of the instant disclosure. Some components may be omitted or rearranged. For example, the first manipulation unit 123 a may be located on another surface of the terminal body, and the second audio output module 152 b may be located on the side surface of the terminal body.

The display unit 151 outputs information processed in the mobile terminal 100. The display unit 151 may be implemented using one or more suitable display devices. Examples of such suitable display devices include a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light emitting diode (OLED), a flexible display, a 3-dimensional (3D) display, an e-ink display, and combinations thereof.

The display unit 151 may be implemented using two display devices, which can implement the same or different display technology. For instance, a plurality of the display units 151 may be arranged on one side, either spaced apart from each other, or these devices may be integrated, or these devices may be arranged on different surfaces.

The display unit 151 may also include a touch sensor which senses a touch input received at the display unit. When a touch is input to the display unit 151, the touch sensor may be configured to sense this touch and the controller 180, for example, may generate a control command or other signal corresponding to the touch. The content which is input in the touching manner may be a text or numerical value, or a menu item which can be indicated or designated in various modes.

The touch sensor may be configured in a form of a film having a touch pattern, disposed between the window 151 a and a display on a rear surface of the window 151 a, or a metal wire which is patterned directly on the rear surface of the window 151 a. Alternatively, the touch sensor may be integrally formed with the display. For example, the touch sensor may be disposed on a substrate of the display or within the display.

The display unit 151 may also form a touch screen together with the touch sensor. Here, the touch screen may serve as the user input unit 123 (see FIG. 1A). Therefore, the touch screen may replace at least some of the functions of the first manipulation unit 123 a.

The first audio output module 152 a may be implemented in the form of a speaker to output voice audio, alarm sounds, multimedia audio reproduction, and the like.

The window 151 a of the display unit 151 will typically include an aperture to permit audio generated by the first audio output module 152 a to pass. One alternative is to allow audio to be released along an assembly gap between the structural bodies (for example, a gap between the window 151 a and the front case 101). In this case, a hole independently formed to output audio sounds may not be seen or is otherwise hidden in terms of appearance, thereby further simplifying the appearance and manufacturing of the mobile terminal 100.

The optical output module 154 can be configured to output light for indicating an event generation. Examples of such events include a message reception, a call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like. When a user has checked a generated event, the controller can control the optical output unit 154 to stop the light output.

The first camera 121 a can process image frames such as still or moving images obtained by the image sensor in a capture mode or a video call mode. The processed image frames can then be displayed on the display unit 151 or stored in the memory 170.

The first and second manipulation units 123 a and 123 b are examples of the user input unit 123, which may be manipulated by a user to provide input to the mobile terminal 100. The first and second manipulation units 123 a and 123 b may also be commonly referred to as a manipulating portion, and may employ any tactile method that allows the user to perform manipulation such as touch, push, scroll, or the like. The first and second manipulation units 123 a and 123 b may also employ any non-tactile method that allows the user to perform manipulation such as proximity touch, hovering, or the like.

FIG. 1B illustrates the first manipulation unit 123 a as a touch key, but possible alternatives include a mechanical key, a push key, a touch key, and combinations thereof.

Input received at the first and second manipulation units 123 a and 123 b may be used in various ways. For example, the first manipulation unit 123 a may be used by the user to provide an input to a menu, home key, cancel, search, or the like, and the second manipulation unit 123 b may be used by the user to provide an input to control a volume level being output from the first or second audio output modules 152 a or 152 b, to switch to a touch recognition mode of the display unit 151, or the like.

As another example of the user input unit 123, a rear input unit (not shown) may be located on the rear surface of the terminal body. The rear input unit can be manipulated by a user to provide input to the mobile terminal 100. The input may be used in a variety of different ways. For example, the rear input unit may be used by the user to provide an input for power on/off, start, end, scroll, control volume level being output from the first or second audio output modules 152 a or 152 b, switch to a touch recognition mode of the display unit 151, and the like. The rear input unit may be configured to permit touch input, a push input, or combinations thereof.

The rear input unit may be located to overlap the display unit 151 of the front side in a thickness direction of the terminal body. As one example, the rear input unit may be located on an upper end portion of the rear side of the terminal body such that a user can easily manipulate it using a forefinger when the user grabs the terminal body with one hand. Alternatively, the rear input unit can be positioned at most any location of the rear side of the terminal body.

Embodiments that include the rear input unit may implement some or all of the functionality of the first manipulation unit 123 a in the rear input unit. As such, in situations where the first manipulation unit 123 a is omitted from the front side, the display unit 151 can have a larger screen.

As a further alternative, the mobile terminal 100 may include a finger scan sensor which scans a user's fingerprint. The controller 180 can then use fingerprint information sensed by the finger scan sensor as part of an authentication procedure. The finger scan sensor may also be installed in the display unit 151 or implemented in the user input unit 123.

The microphone 122 is shown located at an end of the mobile terminal 100, but other locations are possible. If desired, multiple microphones may be implemented, with such an arrangement permitting the receiving of stereo sounds.

The interface unit 160 may serve as a path allowing the mobile terminal 100 to interface with external devices. For example, the interface unit 160 may include one or more of a connection terminal for connecting to another device (for example, an earphone, an external speaker, or the like), a port for near field communication (for example, an Infrared Data Association (IrDA) port, a Bluetooth port, a wireless LAN port, and the like), or a power supply terminal for supplying power to the mobile terminal 100. The interface unit 160 may be implemented in the form of a socket for accommodating an external card, such as Subscriber Identification Module (SIM), User Identity Module (UIM), or a memory card for information storage.

The second camera 121 b is shown located at the rear side of the terminal body and includes an image capturing direction that is substantially opposite to the image capturing direction of the first camera unit 121 a. If desired, second camera 121 a may alternatively be located at other locations, or made to be moveable, in order to have a different image capturing direction from that which is shown.

The second camera 121 b can include a plurality of lenses arranged along at least one line. The plurality of lenses may also be arranged in a matrix configuration. The cameras may be referred to as an “array camera.” When the second camera 121 b is implemented as an array camera, images may be captured in various manners using the plurality of lenses and images with better qualities.

As shown in FIG. 1C, a flash 124 is shown adjacent to the second camera 121 b. When an image of a subject is captured with the camera 121 b, the flash 124 may illuminate the subject.

As shown in FIG. 1B, the second audio output module 152 b can be located on the terminal body. The second audio output module 152 b may implement stereophonic sound functions in conjunction with the first audio output module 152 a, and may be also used for implementing a speaker phone mode for call communication.

At least one antenna for wireless communication may be located on the terminal body. The antenna may be installed in the terminal body or formed by the case. For example, an antenna which configures a part of the broadcast receiving module 111 may be retractable into the terminal body. Alternatively, an antenna may be formed using a film attached to an inner surface of the rear cover 103, or a case that includes a conductive material.

A power supply unit 190 for supplying power to the mobile terminal 100 may include a battery 191, which is mounted in the terminal body or detachably coupled to an outside of the terminal body. The battery 191 may receive power via a power source cable connected to the interface unit 160. Also, the battery 191 can be recharged in a wireless manner using a wireless charger. Wireless charging may be implemented by magnetic induction or electromagnetic resonance.

The rear cover 103 is shown coupled to the rear case 102 for shielding the battery 191, to prevent separation of the battery 191, and to protect the battery 191 from an external impact or from foreign material. When the battery 191 is detachable from the terminal body, the rear case 103 may be detachably coupled to the rear case 102.

An accessory for protecting an appearance or assisting or extending the functions of the mobile terminal 100 can also be provided on the mobile terminal 100. As one example of an accessory, a cover or pouch for covering or accommodating at least one surface of the mobile terminal 100 may be provided. The cover or pouch may cooperate with the display unit 151 to extend the function of the mobile terminal 100. Another example of the accessory is a touch pen for assisting or extending a touch input to a touch screen.

FIG. 2 is a conceptual view of a deformable mobile terminal according to an alternative embodiment of the present invention. In this figure, mobile terminal 200 is shown having display unit 251, which is a type of display that is deformable by an external force. This deformation, which includes display unit 251 and other components of mobile terminal 200, may include any of curving, bending, folding, twisting, rolling, and combinations thereof. The deformable display unit 251 may also be referred to as a “flexible display unit.” In some implementations, the flexible display unit 251 may include a general flexible display, electronic paper (also known as e-paper), and combinations thereof. In general, mobile terminal 200 may be configured to include features that are the same or similar to that of mobile terminal 100 of FIGS. 1A-1C.

The flexible display of mobile terminal 200 is generally formed as a lightweight, non-fragile display, which still exhibits characteristics of a conventional flat panel display, but is instead fabricated on a flexible substrate which can be deformed as noted previously.

The term e-paper may be used to refer to a display technology employing the characteristic of a general ink, and is different from the conventional flat panel display in view of using reflected light. E-paper is generally understood as changing displayed information using a twist ball or via electrophoresis using a capsule.

When in a state that the flexible display unit 251 is not deformed (for example, in a state with an infinite radius of curvature and referred to as a first state), a display region of the flexible display unit 251 includes a generally flat surface. When in a state that the flexible display unit 251 is deformed from the first state by an external force (for example, a state with a finite radius of curvature and referred to as a second state), the display region may become a curved surface or a bent surface. As illustrated, information displayed in the second state may be visual information output on the curved surface. The visual information may be realized in such a manner that a light emission of each unit pixel (sub-pixel) arranged in a matrix configuration is controlled independently. The unit pixel denotes an elementary unit for representing one color.

According to one alternative embodiment, the first state of the flexible display unit 251 may be a curved state (for example, a state of being curved from up to down or from right to left), instead of being in flat state. In this embodiment, when an external force is applied to the flexible display unit 251, the flexible display unit 251 may transition to the second state such that the flexible display unit is deformed into the flat state (or a less curved state) or into a more curved state.

If desired, the flexible display unit 251 may implement a flexible touch screen using a touch sensor in combination with the display. When a touch is received at the flexible touch screen, the controller 180 can execute certain control corresponding to the touch input. In general, the flexible touch screen is configured to sense touch and other input while in both the first and second states.

One option is to configure the mobile terminal 200 to include a deformation sensor which senses the deforming of the flexible display unit 251. The deformation sensor may be included in the sensing unit 140.

The deformation sensor may be located in the flexible display unit 251 or the case 201 to sense information related to the deforming of the flexible display unit 251. Examples of such information related to the deforming of the flexible display unit 251 may be a deformed direction, a deformed degree, a deformed position, a deformed amount of time, acceleration that the deformed flexible display unit 251 is restored, and the like. Other possibilities include most any type of information which can be sensed in response to the curving of the flexible display unit or sensed while the flexible display unit 251 is transitioning into, or existing in, the first and second states.

In some embodiments, controller 180 or other component can change information displayed on the flexible display unit 251, or generate a control signal for controlling a function of the mobile terminal 200, based on the information related to the deforming of the flexible display unit 251. Such information is typically sensed by the deformation sensor.

The mobile terminal 200 is shown having a case 201 for accommodating the flexible display unit 251. The case 201 can be deformable together with the flexible display unit 251, taking into account the characteristics of the flexible display unit 251.

A battery (not shown in this figure) located in the mobile terminal 200 may also be deformable in cooperation with the flexible display unit 261, taking into account the characteristic of the flexible display unit 251. One technique to implement such a battery is to use a stack and folding method of stacking battery cells.

The deformation of the flexible display unit 251 not limited to perform by an external force. For example, the flexible display unit 251 can be deformed into the second state from the first state by a user command, application command, or the like.

In accordance with still further embodiments, a mobile terminal may be configured as a device which is wearable on a human body. Such devices go beyond the usual technique of a user grasping the mobile terminal using their hand. Examples of the wearable device include a smart watch, a smart glass, a head mounted display (HMD), and the like.

A typical wearable device can exchange data with (or cooperate with) another mobile terminal 100. In such a device, the wearable device generally has functionality that is less than the cooperating mobile terminal. For instance, the short-range communication module 114 of a mobile terminal 100 may sense or recognize a wearable device that is near-enough to communicate with the mobile terminal. In addition, when the sensed wearable device is a device which is authenticated to communicate with the mobile terminal 100, the controller 180 may transmit data processed in the mobile terminal 100 to the wearable device via the short-range communication module 114, for example. Hence, a user of the wearable device can use the data processed in the mobile terminal 100 on the wearable device. For example, when a call is received in the mobile terminal 100, the user can answer the call using the wearable device. Also, when a message is received in the mobile terminal 100, the user can check the received message using the wearable device.

FIG. 3 is a perspective view illustrating one example of a watch-type mobile terminal 300 in accordance with another exemplary embodiment. As illustrated in FIG. 3, the watch-type mobile terminal 300 includes a main body 301 with a display unit 351 and a band 302 connected to the main body 301 to be wearable on a wrist. In general, mobile terminal 300 may be configured to include features that are the same or similar to that of mobile terminal 100 of FIGS. 1A-1C.

The main body 301 may include a case having a certain appearance. As illustrated, the case may include a first case 301 a and a second case 301b cooperatively defining an inner space for accommodating various electronic components. Other configurations are possible. For instance, a single case may alternatively be implemented, with such a case being configured to define the inner space, thereby implementing a mobile terminal 300 with a uni-body.

The watch-type mobile terminal 300 can perform wireless communication, and an antenna for the wireless communication can be installed in the main body 301. The antenna may extend its function using the case. For example, a case including a conductive material may be electrically connected to the antenna to extend a ground area or a radiation area.

The display unit 351 is shown located at the front side of the main body 301 so that displayed information is viewable to a user. In some embodiments, the display unit 351 includes a touch sensor so that the display unit can function as a touch screen. As illustrated, window 351 a is positioned on the first case 301 a to form a front surface of the terminal body together with the first case 301 a.

The illustrated embodiment includes audio output module 352, a camera 321, a microphone 322, and a user input unit 323 positioned on the main body 301. When the display unit 351 is implemented as a touch screen, additional function keys may be minimized or eliminated. For example, when the touch screen is implemented, the user input unit 323 may be omitted.

The band 302 is commonly worn on the user's wrist and may be made of a flexible material for facilitating wearing of the device. As one example, the band 302 may be made of fur, rubber, silicon, synthetic resin, or the like. The band 302 may also be configured to be detachable from the main body 301. Accordingly, the band 302 may be replaceable with various types of bands according to a user's preference.

In one configuration, the band 302 may be used for extending the performance of the antenna. For example, the band may include therein a ground extending portion (not shown) electrically connected to the antenna to extend a ground area.

The band 302 may include fastener 302a. The fastener 302 a may be implemented into a buckle type, a snap-fit hook structure, a Velcro® type, or the like, and include a flexible section or material. The drawing illustrates an example that the fastener 302 a is implemented using a buckle.

FIG. 4 is a perspective view illustrating one example of a glass-type mobile terminal 400 according to another exemplary embodiment. The glass-type mobile terminal 400 can be wearable on a head of a human body and provided with a frame (case, housing, etc.) therefor. The frame may be made of a flexible material to be easily worn. The frame of mobile terminal 400 is shown having a first frame 401 and a second frame 402, which can be made of the same or different materials. In general, mobile terminal 400 may be configured to include features that are the same or similar to that of mobile terminal 100 of FIGS. 1A-1C.

The frame may be supported on the head and defines a space for mounting various components. As illustrated, electronic components, such as a control module 480, an audio output module 452, and the like, may be mounted to the frame part. Also, a lens 403 for covering either or both of the left and right eyes may be detachably coupled to the frame part.

The control module 480 controls various electronic components disposed in the mobile terminal 400. The control module 480 may be understood as a component corresponding to the aforementioned controller 180. FIG. 4 illustrates that the control module 480 is installed in the frame part on one side of the head, but other locations are possible.

The display unit 451 may be implemented as a head mounted display (HMD). The HMD refers to display techniques by which a display is mounted to a head to show an image directly in front of a user's eyes. In order to provide an image directly in front of the user's eyes when the user wears the glass-type mobile terminal 400, the display unit 451 may be located to correspond to either or both of the left and right eyes. FIG. 4 illustrates that the display unit 451 is located on a portion corresponding to the right eye to output an image viewable by the user's right eye.

The display unit 451 may project an image into the user's eye using a prism. Also, the prism may be formed from optically transparent material such that the user can view both the projected image and a general visual field (a range that the user views through the eyes) in front of the user.

In such a manner, the image output through the display unit 451 may be viewed while overlapping with the general visual field. The mobile terminal 400 may provide an augmented reality (AR) by overlaying a virtual image on a realistic image or background using the display.

The camera 421 may be located adjacent to either or both of the left and right eyes to capture an image. Since the camera 421 is located adjacent to the eye, the camera 421 can acquire a scene that the user is currently viewing. The camera 421 may be positioned at most any location of the mobile terminal. In some embodiments, multiple cameras 421 may be utilized. Such multiple cameras 421 may be used to acquire a stereoscopic image.

The glass-type mobile terminal 400 may include user input units 423 a and 423 b, which can each be manipulated by the user to provide an input. The user input units 423 a and 423 b may employ techniques which permit input via a tactile input. Typical tactile inputs include a touch, push, or the like. The user input units 423 a and 423 b are shown operable in a pushing manner and a touching manner as they are located on the frame part and the control module 480, respectively.

If desired, mobile terminal 400 may include a microphone which processes input sound into electric audio data, and an audio output module 452 for outputting audio. The audio output module 452 may be configured to produce audio in a general audio output manner or an osteoconductive manner. When the audio output module 452 is implemented in the osteoconductive manner, the audio output module 452 may be closely adhered to the head when the user wears the mobile terminal 400 and vibrate the user's skull to transfer sounds.

In the following description, embodiments related to a controlling method implemented in the above-configured mobile terminal shall be explained with reference to the accompanying drawings.

With reference to FIGS. 5 to 22, a process, which includes the steps of recognizing at least one object included in an image displayed on a screen, searching for at least one associated information on the recognized object using a partial image corresponding to the recognized object as a search word, and providing the found at least one associated information to a user, according to the present invention is described in detail as follows.

FIG. 5 is a flowchart for a method of controlling a mobile terminal according to one embodiment of the present invention.

FIGS. 6 to 22 are diagrams to describe a method of controlling a mobile terminal according to one embodiment of the present invention.

Referring to FIGS. 5 to 22, the controller 180 of the mobile terminal 100 displays an image including at least one object on a screen of the touchscreen 151 [S110].

In this case, the image including the at least one object can include at least one of an image currently captured through the camera 121, an image saved in the memory 170 by being previously captured through the camera 121, an image saved in the memory 170 by being downloaded from a webpage, an image received from at least one counterpart terminal in the course of a message chat with the at least one counterpart terminal, an image included in a currently accessed and displayed webpage, an image displayed through a gallery function of the mobile terminal 100, and the like.

If the corresponding image is displayed, the controller 180 recognizes the at least one object included in the image [S120].

In particular, the controller 180 recognizes a shape of the at least one object included in the image using an object shape recognition algorithm and is then able to save a feature value of the recognized object in the memory 170.

On the other hand, if an image is displayed on a screen, the controller 180 can recognize all objects included in the image or at least one object corresponding to a part selected from the image by a user. Moreover, the controller 180 can recognize at least one object included in a region designated within the image by a user or at least one object located nearby a point touched by a user within the image.

If at least one object is recognized from the image, as shown in FIG. 6, the controller 180 can give a visual effect to the recognized object so that a user can identify the recognized object within the image.

FIG. 6 shows that 1^(st) to 3^(rd) objects 510, 520 and 530 in an image 500 are recognized, that the recognized 1^(st) to 3^(rd) objects 510, 520 and 530 are identifiably displayed within the image 500, that the 2^(nd) object 520 is the Eiffel Tower, and that the 3^(rd) object 530 is a wristwatch.

For instance, referring to FIG. 6( a), the controller 180 controls an outline in specific color to be displayed on a frame of each of the 1^(st) to 3^(rd) objects 510, 520 and 530 so as to visually inform a user of a result of recognition of each of the 1^(st) to 3^(rd) objects 510, 520 and 530 within the currently displayed image 500.

For another instance, referring to FIG. 6( b), the controller 180 controls a highlight in specific color to be displayed on a region, in which each of the 1^(st) to 3^(rd) objects 510, 520 and 530 is displayed, so as to visually inform a user of a result of recognition of each of the 1^(st) to 3^(rd) objects 510, 520 and 530 within the currently displayed image 500.

Moreover, the controller 180 can visually inform a user of a result of recognition of each of the 1^(st) to 3^(rd) objects 510, 520 and 530 within the currently displayed image 500 in a manner of controlling the 1^(st) to 3^(rd) objects 510, 520 and 530 recognized within the image 500 to be displayed by being projected from the image 500, controlling the to 3^(rd) objects 510, 520 and 530 to be displayed by being converted 3-dimensionally, or controlling the 1^(st) to 3^(rd) objects 510, 520 and 530 to be displayed by being enlarged in size greater than a previous size.

Referring now to FIG. 5, if the at least one object in the image is recognized by the step S120, the controller 180 extracts a partial image corresponding to the recognized object from the image [S130]. In particular, the controller 180 can extract the partial image corresponding to the recognized object from the image by cropping or copying a display region of the recognized object in the image.

The controller 180 searches for at least one associated information associated with the object corresponding to the partial image using the extracted partial image as a search word [S140].

In doing so, the controller 180 can search informations saved in the memory 170 for the at least one associated information on the object corresponding to the partial image. And, the controller 180 is able to search for the at least one associated information on the object corresponding to the partial image through a web browser providing an image search function by being accessed through the wireless communication unit 110.

In this case, as the associated information found by the controller 180 through the memory 170 or the web browser, the controller 180 can search for at least one of at least one information including the partial image, at least one information associated with the information including the partial image, at least one information associated with the partial image, at least one information associated with the information associated with the partial image, at least one information associated with the information including an image associated with the partial image, at least one information associated with an acquired time and place of the image, and the like.

For instance, if the partial image of the object indicates ‘T-shirt’, the controller 180 can search the memory 160 or the web browser for all informations including the same image of the ‘T-shirt’ as the associated information of the ‘T-shirt’.

For another instance, if the same information of the ‘T-shirt’ is primarily found from the memory 160 or the web browser, the controller 180 180 can search the memory 160 or the web browser again for an information associated with the primarily found information as a final associated information of the ‘T-shirt’. In doing so, the controller 180 can perform the search task using an association search algorithm.

For another instance, the controller 180 can search the memory 160 or the web browser for an information associated with the ‘T-shirt’ as an associated information of the ‘T-shirt’. If the information associated with the ‘T-shirt’ is primarily found from the memory 160 or the web browser, the controller 180 180 can search the memory 160 or the web browser again for an information further associated with the primarily found information as a final associated information of the ‘T-shirt’.

For another instance, the controller 180 can search the memory 160 or the web browser for information including an image associated with the ‘T-shirt’ as an associated information of the ‘T-shirt’. If the information including the image associated with the ‘T-shirt’ is primarily found from the memory 160 or the web browser, the controller 180 180 can search the memory 160 or the web browser again for an information further associated with the primarily found information as a final associated information of the ‘T-shirt’.

For further instance, the controller 180 can search the memory 160 or the web browser for an information associated with an acquired time and place of the image including the ‘T-shirt’ as associated information of the ‘T-shirt’.

In this case, if the image includes an image captured by the camera 121, a time on having the image captured by the camera 121 and a location of the mobile terminal 100 on having the image captured by the camera 121 can become the acquired time and place of the image, respectively. Alternatively, if the image includes an image saved in the memory 160, a time on saving the image in the memory 160 and a location of the mobile terminal 100 on saving the image in the memory 160 can become the acquired time and place of the image, respectively. Alternatively, if the image includes an image downloaded from the webpage, a time on downloading the image from the webpage and a location of the mobile terminal 100 on downloading the image from the webpage can become the acquired time and place of the image, respectively. In particular, for example, if an object in a moon or sun shape is recognized from the image, a weather forecast on acquiring the image can be found as associated information of the object in the moon or sun shape based on the acquired time and location of the image.

Referring now to FIG. 5, if the at least one associated information on the object corresponding to the partial image is found by the step S140, the controller 180 controls the found associated information to be displayed on the touchscreen 151 [S150].

In the following description, the step S150 shown in FIG. 3 shall be described in detail with reference to FIGS. 7 to 16.

First of all, referring to FIG. 7, the controller 180 recognizes all objects 510, 520 and 530 within an image 500 without a user's action of selection of at least one object within the image 500 [FIG. 7( a)].

The controller 180 extracts partial images respectively corresponding to the recognized objects 510, 520 and 530, respectively. The controller 180 searches for associated informations 610, 620 and 630 associated with the objects 510, 520 and 530 corresponding to the partial images using the extracted partial images as search words, respectively. And, the controller 180 displays the found associated informations 610, 620 and 630 [FIG. 7( b)].

In doing so, if the associated informations 610, 620 and 630 are found, the controller 180 switches a screen having the image 500 displayed thereon to a search result screen including the associated informations 610, 620 and 630 and is then able to display the search result screen. If the associated informations 610, 620 and 630 are found, the controller 180 can control the associated informations 610, 620 and 630 to be displayed on the image displayed screen in a manner of overlaying the image displayed screen. If the associated informations 610, 620 and 630, the controller 180 can control the associated informations 610, 620 and 630 to be displayed as a popup window on the image displayed screen.

For instance, among the associated informations 610, 620 and 630, the 1^(st) associated information 610 is the associated information of the 1^(st) object ‘T-shire’ 510 among the recognized objects 510, 520 and 530, the 2^(nd) associated information 620 is the associated information of the 2^(nd) object ‘Eiffel Tower’ 520 among the recognized objects 510, 520 and 530, and the 3^(rd) associated information 630 is the associated information of the 3^(rd) object ‘wristwatch’ 530 among the recognized objects 510, 520 and 530.

In this case, if it is impossible to display all the found associated informations 610, 620 and 630 on the screen, the controller 180 displays portions of the associated informations 610, 620 and 630 only. If a specific associated information is selected from the partially displayed associated informations 610, 620 and 630, the controller 180 can display a full content of the selected associated information. The portions of the associated informations 610, 620 and 630 can include at least one of partial text contents of the associated informations 610, 620 and 630, titles of the associated informations 610, 620 and 630, summarizes of the contents of the associated informations 610, 620 and 630, and hyperlinks of the associated informations 610, 620 and 630, respectively.

Referring to FIG. 8, the controller 180 recognizes all objects 510, 520 and 530 in an image 500. If a user selects at least one object ‘T-shirt’ 510 from the recognized objects 510, 520 and 530 [FIG. 8( a)]. The controller 180 extracts a partial image corresponding to the selected object 510 from the image 500, searches for at least one associated information 610 associated with the object 510 corresponding to the partial image using the extracted partial image as a search word, and then displays the found associated information 610 [FIG. 8( b)].

Referring to FIG. 9, if a user designates a specific region within an image 500, the controller 180 recognizes at least one object ‘T-shirt’ 510 included in the designated specific region and then identifiably displays the recognized object 510 within the image [FIG. 9( a)].

For instance, if a drag touch gesture having a pattern for designating the specific region is inputted to the image 500 by a user, the controller 180 recognizes the at least one object 510 existing within the region designated by the pattern of the inputted drag touch gesture.

Subsequently, the controller 180 extracts a partial image corresponding to the recognized object 510 from the image 500, searches for at least one associated information 610 associated with the object 510 corresponding to the partial image using the extracted partial image as a search word, and then displays the found associated information 610 [FIG. 9( b)].

While all objects 510, 520 and 530 within the image 500 are recognized, if a specific region within the image 500 is designated, the controller 180 extracts a partial image corresponding to the at least one object ‘T-shirt’ 510 included in the designated region from the image 500, searches for at least one associated information 610 associated with the object 510 corresponding to the partial image using the extracted partial image as a search word, and is then able to display the found associated information 610.

Referring to FIG. 10, while all objects 510, 520 and 530 within an image 500 are recognized, if a pinch-in touch gesture is inputted to the image 500 and then released, the controller 180 recognizes that all the objects 510, 520 and 530 included in the image 500 are selected [FIG. 10( a)], extracts partial images respectively corresponding to the recognized objects 510, 520 and 530 from the image 500, searches for associated informations 610, 620 and 630 associated with then objects 510, 520 and 530 corresponding to the partial images using the extracted partial images as search words, respectively, and then displays the found associated informations 610, 620 and 630 [FIG. 10( b)].

In particular, a user is able to sequentially select all the objects 510, 520 and 530 within the image 500 by applying a pinch-in touch gesture of gathering two fingers together to the image 500 from which the objects 510, 520 and 530 are recognized. While all the objects 510, 520 and 530 within the image 500 are selected using the pinch-in touch gesture, if a pinch-out touch gesture of spreading out two fingers is applied to the image 500, all of the selected objects 510, 520 and 530 can be sequentially released from the selection.

FIGS. 11 to 14 show a process as follows. First of all, if at least one associated information on at least one object recognized from an image 500 is found, a screen of the touchscreen 151 is partitioned into at least two regions including a 1^(st) region and a 2^(nd) region. The image 500 is displayed on the 1^(st) region. And, the found associated information is displayed on the 2^(nd) region.

For instance, FIG. 11( a) shows that a screen of the touchscreen 151 is in portrait mode and also shows that an image 500 including objects 510, 520 and 530 is displayed on the screen in the portrait mode.

The controller 180 recognizes all the objects 510, 520 and 530 within the image 500, extracts partial images corresponding to the recognized objects 510, 520 and 530 from the image 500, and then searches for associated informations 610, 620 and 630 associated with the objects 510, 520 and 530 corresponding to the partial images using the extracted partial images as search words, respectively.

Subsequently, referring to FIG. 11( b), the controller 180 partitions the screen of the touchscreen 151 into a 1^(st) region (e.g., a top region) and a 2^(nd) region (e.g., a bottom region), displays the image 500 on the 1^(st) region and also displays the found associated informations 610, 620 and 630 on the 2^(nd) region.

For another instance, FIG. 12( a) shows that a screen of the touchscreen 151 is in landscape mode and also shows that an image 500 including objects 510, 520 and 530 is displayed on the screen in the portrait mode.

The controller 180 recognizes all the objects 510, 520 and 530 within the image 500, extracts partial images corresponding to the recognized objects 510, 520 and 530 from the image 500, and then searches for associated informations 610, 620 and 630 associated with the objects 510, 520 and 530 corresponding to the partial images using the extracted partial images as search words, respectively.

Subsequently, referring to FIG. 12( b), the controller 180 partitions the screen of the touchscreen 151 into a 1^(st) region (e.g., a left region) and a 2^(nd) region (e.g., a right region), displays the image 500 on the 1^(st) region and also displays the found associated informations 610, 620 and 630 on the 2^(nd) region.

Referring to FIG. 13( a), while all objects 510, 520 and 530 in an image are recognized, if the 1^(st) object 510 is selected, the controller 180 extracts a partial image corresponding to the selected 1^(st) object 510 from the image 500 and then searches for at least one associated information 610 of the 1^(st) object 510 corresponding to the partial image using the extracted partial image as a search word.

Referring to FIG. 13( b), the controller 180 partitions a screen of the touchscreen 151 into a 1^(st) region and a 2^(nd) region and then controls the image 500 and the associated information on the 1^(st) object 510 to be displayed on the 1^(st) region and the 2^(nd) region, respectively.

Moreover, referring to FIG. 13( b), while the associated information 601 of the 1^(st) object 510 is displayed on the 2^(nd) region, if the recognized 2^(nd) object 520 is selected from the image 500 displayed on the 1^(st) region, the controller 180 extracts a partial image corresponding to the selected 2^(nd) object 520 from the image 500 and then searches for at least one associated information 620 of the 2^(nd) object 520 corresponding to the partial image using the extracted partial image as a search word.

Referring to FIG. 13( c), the controller 180 controls the associated information 620 on the 2^(nd) object 520 to be displayed on the 2^(nd) region, on which the associated information 610 on the 1^(st) object 510 is displayed, by being updated.

Moreover, referring to FIG. 13( c), while the associated information 610 on the 1^(st) object 510 and the associated information 620 on the 2^(nd) object 520 are displayed on the 2^(nd) region, if the recognized 3^(rd) object 530 is selected from the image 500 displayed on the 1^(st) region, the controller 180 extracts a partial image corresponding to the selected 3^(rd) object 530 from the image 500 and then searches for at least one associated information 630 of the 3^(rd) object 530 corresponding to the partial image using the extracted partial image as a search word.

Referring to FIG. 13( d), the controller 180 controls the associated information on the 3^(rd) object 530 to be displayed on the 2^(nd) region, on which the associated information 610 on the 1^(st) object 510 and the associated information 620 on the 2^(nd) object 520 are displayed, by being updated.

FIG. 14 shows a following process. First of all, if a plurality of associated informations on at least one object in an image 500 are found and it is impossible to display all of the found associated informations within the 2^(nd) region, the controller 180 controls a list of items respectively indicating the found associated informations to be displayed within the 2^(nd) region. If at least one specific item is selected from the list, the controller 180 displays full contents of the associated information corresponding to the selected item.

In particular, referring to FIG. 14( a), the controller 180 recognizes all objects 510, 520 and 530 in an image 500 and then searches for associated informations 610, 620 and 630 on all of the recognized objects 510, 520 and 530 or at least one or more objects 510, 520 and 530 selected by a user.

Referring to FIG. 14( b), the controller 180 partitions a screen of the touchscreen 151 into at least two regions including a 1^(st) region and a 2^(nd) region, controls the image 500 to be displayed on the 1^(st) region, and then determines whether the found associated informations 610, 620 and 630 can be fully displayed within the 2^(nd) region.

If the found associated informations 610, 620 and 630 can be fully displayed within the 2^(nd) region, the controller 180 controls all of the found associated informations 610, 620 and 630 to be displayed within the 2^(nd) region.

On the contrary, if found associated informations 610, 620 and 630 cannot be fully displayed within the 2^(nd) region, referring to FIG. 14( b), the controller 180 controls a list of items 610A, 620A and 630A, which respectively indicate the found associated informations 610, 620 and 630, to be displayed within the 2^(nd) region.

In this case, each of the items 610A, 620A and 630A can be configured with a combination of at least one or two of a thumbnail indicating a corresponding one of the found associated informations 610, 620 and 630, a partial image of a corresponding one of the objects, a title of a corresponding one of the objects, a summary of a corresponding one of the objects, and a partial text of a corresponding one of the objects.

For instance, referring to FIG. 14( b), in the configuration of the 1^(st) item 610A indicating the associated information 610 of the 1^(st) object 510, a partial image of the 1^(st) object 510 is displayed as a background and a title indicating the 1^(st) object 510 is displayed within the background. And, in the configuration of the 2^(nd) item 620A indicating the associated information 620 of the 2^(nd) object 520, a partial image of the 2^(nd) object 520 is displayed as a background and a title indicating the 2^(nd) object 520 is displayed within the background. Moreover, in the configuration of the 3^(rd) item 630A indicating the associated information 630 of the 3^(rd) object 530, a partial image of the 3^(rd) object 530 is displayed as a background and a title indicating the 3^(rd) object 530 is displayed within the background.

If the specific item 620A is selected from the list [FIG. 14( b)], the controller 180 displays the associated information 620 corresponding to the selected specific item 620A on the 2^(nd) region.

FIG. 15 shows a process as follows. First of all, after the controller 180 has searched for an associated information on at least one object in an image 500 displayed on a screen, if the image displayed screen is touched and flicked in a 1^(st) direction, the controller 180 switches the image displayed screen to a screen including the found associated information and then displays the associated information included screen. If the associated information included screen is touched and dragged in a 2^(nd) direction opposite to the 1^(st) direction, the controller 180 switches the associated information included screen to the image displayed screen and then displays the image included screen.

In particular, referring to FIG. 15( a), the controller 180 recognizes all objects 510, 520 and 530 within an image 500 displayed on a 1^(st) screen and then searches for associated informations 610, 620 and 630 on all of the recognized objects 510, 520 and 530 or at least one or more objects 510, 520 and 530 selected by a user.

If a 1^(st) touch gesture of touching and flicking the 1^(st) screen having the image 500 displayed thereon in a 1^(st) direction (e.g., a right direction) is inputted, referring to FIG. 15( b), the controller 180 switches the 1^(st) screen having the image 500 displayed thereon to a 2^(nd) screen including the found associated informations 610, 620 and 630 and then displays the 2^(nd) screen.

If a 2^(nd) touch gesture of touching and flicking the 2^(nd) screen including the found associated informations 610, 620 and 630 in a 2^(nd) direction (e.g., a left direction) opposite to the 1^(st) direction, the controller 180 switches the 2^(nd) screen including the associated informations 610, 620 and 630 to the 1^(st) screen including the image 500 and then displays the 1^(st) screen.

FIG. 16 shows a process as follows. First of all, after the controller 180 has searched for an associated information on at least one object included in an image 500 displayed on a screen, the controller 180 controls an indicator indicating the found associated information to be displayed on the corresponding object within the image before displaying the found associated information. Secondly, if the indicator is selected, the controller 180 displays the associated information corresponding to the indicator.

In this case, the indicator can include at least one of a partial information of the corresponding associated information, an information on summarizing the corresponding associated information, a title of the corresponding associated information, a hyperlink of the corresponding associated information, a location information on a location at which the corresponding associated information is found, an acquired time of an image including an object corresponding to the corresponding associated information, an acquired location of the image including the object corresponding to the corresponding associated information, and the like.

The location information of the corresponding associated information is the location information on the location at which the associated information is found. If the corresponding associated information is found at a specific folder in the memory 170, the location information of the corresponding associated information can include information indicating a location of the folder. If the corresponding associated information is found through a web browser, the location information of the corresponding associated information can include at least one of a URL of the web browser, an icon indicating the web browser, a URL of a webpage disclosing the corresponding associated information, and the like.

If the image 500 including the object corresponding to the corresponding associated information is photographed through the camera 121, the acquired time and location of the image 500 can include time information of a timing point at which the image 500 is photographed and a location information of the mobile terminal 100 at the timing point. If the image 500 includes an image downloaded from a webpage, the acquired time and location can include timing information of a timing point of downloading the image and a location information of the mobile terminal 100 at the timing point.

In particular, referring to FIG. 16( a), the controller 180 recognizes all objects 510, 520 and 530 within an image 500 and then searches for associated informations 610, 620 and 630 on all of the recognized objects 510, 520 and 530 or at least one or more objects 510, 520 and 530 selected by a user.

Before displaying the found associated informations 610, 620 and 630, the controller 180 controls 1^(st) to 3^(rd) indicators indicating the found associated informations 610, 620 and 630 to be displayed on the corresponding objects 510, 520 and 530 in the image 500, respectively.

For instance, in FIG. 16( a), the 1^(st) to 3^(rd) indicators indicate partial text informations 610B, 620B and 630B of the contents of the corresponding associated informations 610, 620 and 630, respectively.

If a specific indicator is selected from the 1^(st) to 3^(rd) indicators, the controller 180 displays a full content of the associated information corresponding to the selected indicator.

FIG. 16( b) shows that the 1^(st) to 3^(rd) indicators indicate title informations 610C, 620C and 630C of the contents of the corresponding associated informations 610, 620 and 630, respectively.

FIG. 16( c) shows that informations 540A and 540B associated with the acquired time and location of the image 500 are displayed as the found associated informations within the image 500.

For instance, if the acquired time of the image is ‘2012. 07. 25, 15:05’ and the acquired location of the image 500 is ‘Eiffel Tower, Paris France’, the controller 180 searches for a current weather forecast information 540A according to the acquired location of the image 500 through the web browser or a weather forecast application installed on the mobile terminal 100 and is then able to display the found information 540A as the associated information associated with the acquired time and location of the image 500.

The controller 180 searches for a weather forecast information 540B at the timing point of acquiring the image 500 based on the acquired time and location of the image 500 through the web browser or the weather forecast application installed on the mobile terminal 100 and is then able to display the found information 540B as the associated information associated with the acquired time and location of the image 500.

Referring now to FIG. 5, after finding and displaying the at least one associated information on the at least one object within the image 500 by the steps S110 to 5150, if a command for saving the associated information is inputted by a user, the controller 180 controls the found associated information to be saved in the memory 160 in a manner of tagging the corresponding object within the image 500 [S160].

In particular, the controller 180 controls the found associated information and a shape feature value of the at least one object corresponding to the found associated information to be saved in the memory 170 in a manner of being mapped to each other.

Thereafter, if the image 500 tagged by the associated information is displayed again on the touchscreen 151, the controller 180 controls the tagging associated information to be displayed on the corresponding object in the image 500.

In the following description, the step 5160 shown in FIG. 5 shall be explained in detail with reference to FIGS. 17 to 22.

First of all, referring to FIG. 17, if a display command for displaying the image 500 saved by the step S160 shown in FIG. 5 is inputted, the controller 180 checks whether at least one associated information tagging the image 500 or at least one or more objects 510, 520 and 530 in the image 500 exists in the memory 160 before displaying the image 500.

As a result of the check, if at least one or more associated informations 610, 620 and 630 tagging the image 500 or the at least one or more objects 510, 520 and 530 exists in the memory 160, the controller 180 displays the found associated informations 610, 620 and 630. In doing so, the found associated informations 610, 620 and 630 can be displayed on the corresponding objects in the image 500, respectively.

The controller 180 is able to transmit the image 500 including the associated informations 610, 620 and 630 to at least one counterpart terminal designated by a user. In particular, the user of the mobile terminal 100 transmits the associated information on the at least one object within the image in a manner of tagging the image 500 with the associated information on the at least one object, thereby sharing informations with a user of the counterpart terminal.

In more particular, if a transmission command 710 for transmitting the image 500 tagged with the associated informations 610, 620 and 630 is inputted by a user, the controller 180 displays a contact list of at least one counterpart terminal which will receive the image 500 tagged with the associated informations 610, 620 and 630 and then transmits the image 500 tagged with the associated informations 610, 620 and 630 to a contact of the at least one counterpart terminal.

Subsequently, referring to FIG. 18( a), if a display command for displaying the image 500 saved by the step 5160 shown in FIG. 5 is inputted, the controller 180 displays the image 500.

If at least one object 510 is selected from the image 500, the controller 180 recognizes a shape of the selected object 510, searches the memory 160 for at least one associated information 610 tagged with a shape feature value corresponding to the recognized shape of the object 510, and then displays the found associated information 610.

For instance, referring to FIG. 18( b), before the controller 180 displays the found associated information 610, as mentioned in the foregoing description with reference to FIG. 16, the controller 180 controls an indicator 610B, which indicates the found associated information 610, to be displayed on the selected object 510.

Thereafter, referring to FIG. 18( c) and FIG. 18( d), if the indicator 610B displayed on the object 510 is selected, the controller 180 switches a 1^(st) screen including the image 500 to a 2^(nd) screen including the found associated information 610 and then displays the 2^(nd) screen [FIG. 18( c)]. Alternatively, the controller 180 partitions a screen of the touchscreen 151 into at least two regions including a 1^(st) region and a 2^(nd) region and then displays the image 500 and the found associated information 610 on the 1^(st) region and the 2^(nd) region, respectively [FIG. 18( d)].

Subsequently, referring to FIG. 19( a), if a display command for displaying the image 500 saved by the step S160 shown in FIG. 5 is inputted, the controller 180 displays the image 500.

If at least one 1^(st) object 510 is selected from the image 500, the controller 180 recognizes a shape of the selected 1^(st) object 510, searches the memory 160 for at least one 1^(st) associated information 610 tagged with a shape feature value corresponding to the recognized shape of the 1^(st) object 510, and then controls the found 1^(st) associated iformation 610 to be outputted in a manner of being converted to a speech using a TTS (text to speech) function [FIG. 19( b)].

Subsequently, if at least one 2^(nd) object 520 is selected from the image 500, the controller 180 recognizes a shape of the selected 2^(nd) object 520, searches the memory 160 for at least one 2^(nd) associated information 620 tagged with a shape feature value corresponding to the recognized shape of the 2^(nd) object 520, and then controls the found 2^(nd) associated information 620 to be outputted in a manner of being converted to a speech using a TTS (text to speech) function [FIG. 19( c)].

Subsequently, if at least one 3^(rd) object 530 is selected from the image 500, the controller 180 recognizes a shape of the selected 3^(rd) object 530, searches the memory 160 for at least one 3^(rd) associated information 630 tagged with a shape feature value corresponding to the recognized shape of the 3^(rd) object 530, and then controls the found 3^(rd) associated information 630 to be outputted in a manner of being converted to a speech using a TTS (text to speech) function [FIG. 19( d)].

Meanwhile, referring to FIG. 20 and FIG. 21, while objects in an image 500 are recognized, if at least one object is selected from the recognized objects and a memo content is inputted onto the image 500 by a user, the controller 180 saves the inputted memo content in a manner of tagging the selected object with the inputted memo content. If the memo content tagged image 500 is displayed on the touchscreen 151 again, the controller 180 can control the tagged memo content on the corresponding object in the image 500.

For instance, after the controller 180 has recognized objects 510, 520 and 530 in the image 500, if a user selects at least one object 510 [FIG. 20( a)], the controller 180 displays a memo window 720 for inputting a memo content with which the object 510 will be tagged [FIG. 20( b)].

If a memo content 721 with which the object 510 will be tagged is inputted to the memo window 720, referring to FIG. 20( d), the controller 180 saves the memo content 721 inputted through the memo window 720 in the memory 160 in a manner of tagging the image 500 or the selected object 510 with the inputted memo content 721.

On the other hand, after the controller 180 has recognized the objects 510, 520 and 530 in the image 500, if a user selects at least one object 510 and a handwritten memo content 730 with which the object 510 will be tagged is inputted through a user's finger or a touch pen [FIG. 20( c)], the controller 180 saves the inputted handwritten memo content 730 in the memory 160 in a manner of tagging the image 500 or the selected object 510 with the inputted handwritten memo content 730 [FIG. 20( d)].

Referring to 21(a), if a display command for displaying the image 500 saved by the process shown in FIG. 20 is inputted, the controller 180 checks whether at least memo content 730 with which the image 500 or the at least one object 510 is tagged exists in the memory 160 before displaying the image 500.

As a result of the check, if the at least memo content 730 with which the image 500 or the at least one object 510 is tagged exists in the memory 160, the controller 180 controls the memo content 730 to be displayed on the image 500 or the corresponding object 510 in the image 500.

And, the controller 180 can transmit the image 500 including the memo content 730 to at least one counterpart terminal designated by a user. In particular, the user of the mobile terminal 100 transmits the memo content of the at least one object in the image 500 in a manner of tagging the image 500 with the memo content, thereby sharing information with the user of the counterpart terminal.

Referring to FIG. 21( b), if a display command for displaying the image 500 saved by the process shown in FIG. 20 is inputted, the controller 180 displays the image 500.

Thereafter, if at least one object 510 is selected from the image 500, the controller 180 recognizes a shape of the selected object 510, searches the memory 160 for at least one memo content 721 tagged with a shape feature value corresponding to the recognized shape of the object 510, and then displays the found memo content on the selected object 510.

FIG. 22 shows a process as follows. First of all, if an image tagged with an associated information (or a memo content) by one of the processes shown in FIGS. 17 to 21 is displayed again and at least one object is then selected from the image, the controller 180 acquires and displays at least one search word associated with the associated information with which the object is tagged. If the displayed search word is selected, an associated information of the selected search word is found and displayed.

Referring to FIG. 22( a), if a display command for displaying an image 500 tagged with an associated information (or a memo content) by one of the processes shown in FIGS. 17 to 21 is inputted, the controller 180 displays the image 500.

Subsequently, if at least one object 510 is selected from the image 500, the controller 180 recognizes a shape of the selected object 510, searches the memory 160 for at least one assoicae4d information 630 tagged with a shape feature value corresponding to the recognized shape of the object 530, and then acquires and displays at least one or more associated search words 741 to 744 associated with the found associated information 630 [FIG. 23( b)].

For instance, the controller 180 can acquire the at least one or more associated search words 741 to 744 associated with the found associated information 630 through the web browser. In FIG. 22, the associated search words 741 to 744 associated with the associated information 630 on the object ‘wristwatch’ 530 include ‘watch’ 741, ‘watch by Company A’ 742, ‘watch by Company B’ 743 and ‘watch by Company C’ 744.

If at least one associated search word 742 is selected from the acquired associated search words 741 to 744, referring to FIG. 24( c), the controller 180 searches the memory 160 or the web browser for at least one associated information 741A associated with the selected associated search word 742 and then displays the found at least one associated search word 741A.

Accordingly, embodiments of the present invention provide various effects and/or features.

According to at least one of embodiments of the present invention, when a user searches for an information on a specific object in an image using an image search function, it is unnecessary for the user to crop a partial image corresponding to the specific object in the image one by one. Instead, a mobile terminal automatically recognizes the specific object in the image and is then able to search for at least one associated information on the specific object using a partial image of the automatically recognized specific object.

According to at least one of embodiments of the present invention, after at least one associated information found for a specific object in an image has been saved in a manner of tagging the specific object and/or the image with the found at least one associated information, when a user watches the image again later, the associated image with which the image is tagged is displayed together with the image. Therefore, a user can use both of the image and the associated information together.

According to at least one of embodiments of the present invention, at least one associated information found for a specific object is displayed on a screen on which an image including the specific object is displayed together with the image. Therefore, a user can use both of the image and the associated information on the specific object in the image within a single screen without switching a current image displayed screen to a screen including the found associated information.

Various embodiments may be implemented using a machine-readable medium having instructions stored thereon for execution by a processor to perform various methods presented herein. Examples of possible machine-readable mediums include HDD (Hard Disk Drive), SSD (Solid State Disk), SDD (Silicon Disk Drive), ROM, RAM, CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, the other types of storage mediums presented herein, and combinations thereof. If desired, the machine-readable medium may be realized in the form of a carrier wave (for example, a transmission over the Internet). The processor may include the controller 180 of the mobile terminal.
